Tidal HIFI has been my main source of music since I subscribed. Via their desktop app with the volume set to the maximum it streams a bit perfect 16/44. The 16 word-length LED on the Benchmark DAC2 is proof that no manipulation is being done by the computer. The catalogue is impressive too, except maybe for classical music.
